The perimeter of the square is 20 cm. This square is divided into 2 rectangles. Find the perimeter and area of this rectangle.

All sides of the square are equal, so the perimeter of the square is equal to its side multiplied by 4. Calculate the side of this square, taking into account that its perimeter is 20 cm:
20/4 = 5 centimeters.
Based on the condition of the problem, the square was cut into two equal rectangles. That is, two opposite sides of the square were divided in half and each part became equal:
5/2 = 2.5 cm.
Thus, we got two rectangles with a length of 5 cm and a width of 2.5 cm.The perimeter of one such rectangle is:
2 * (5 + 2.5) = 15 cm.
The area of the rectangle is:
2.5 * 5 = 12.5 cm².
